The V4-R8 is an ESP32-S3R8 with 8 MB octal PSRAM, where V4 and V4.3 are S3R2
with 2 MB quad. Octal PSRAM claims GPIO33-37, which moves Vext 36->40, the LED
35->46 and VGNSS_Ctrl 34->42, and drops ADC_Ctrl and GNSS_RST. CTX binds as
lna-bypass-gpios rather than tx-enable-gpios, so the board is a fourth one
where set radio.fem.rxgain works; the CLI reference and the register-patch help
text say so.
The allowlist change is needed for the board to be added correctly. CMake
MATCHES is a substring search, so the existing heltec_wifi_lora32_v4 entry also
matches heltec_wifi_lora32_v4_r8 and the new board would get CONFIG_PM=y
without anyone deciding it should, on a path pm_esp32.conf marks as not yet
validated on hardware. Anchoring preserves the five boards that were intended
to match, including heltec_wireless_tracker_v2, which previously qualified only
by substring and is now listed explicitly.

Add the MeshCore Room Server role to ZephCore — a store-and-forward
shared message room. Clients log in with an admin or guest password
and post messages; the server pushes each new post to all other
logged-in clients (round-robin, per-client sync cursor, ACK + retry,
3-strike eviction).
Ported from upstream MeshCore's simple_room_server, structured as a
near-clone of RepeaterMesh so it reuses the proven ACL, region
filtering, CLI, adverts and telemetry; the post buffer + push engine
are the only net-new pieces:
- RoomServerMesh: PostInfo ring (MAX_UNSYNCED_POSTS=32), addPost,
pushPostToClient, getUnsyncedCount, processAck, onAckRecv, the
loop() push driver; room login (onAnonDataRecv parses the
sync_since cursor); posts/admin-CLI/keep-alive (onPeerDataRecv);
ADV_TYPE_ROOM advert; ServerStats wire layout; disable_fwd=1.
- main_room_server.cpp: event-loop entry (USB serial CLI, no BLE).
- Kconfig: ZEPHCORE_ROLE_ROOM_SERVER + ZEPHCORE_MAX_UNSYNCED_POSTS.
- CMakeLists role gating; boards/common/room_server.conf.
Post frame, SHA-256 ACK and login-reply layouts match upstream for
MeshCore app compatibility. Builds for gat562_30s
(FLASH 30.95% / RAM 32.46%). Not yet hardware-tested.
553b71c made production the default but broke configure+link:
- ZEPHCORE_COMPANION_USB sat inside the role choice (recursive dep)
- CONFIG_RESET_ON_FATAL_ERROR was an undefined, unimplemented symbol
- USB companion sources still gated on CONFIG_LOG, not ZEPHCORE_USB_STACK
Move the USB toggle out of the choice, add a real
ZEPHCORE_RESET_ON_FATAL_ERROR Kconfig + k_sys_fatal_error_handler that
cold-reboots, and match the CMake USB guard to ZEPHCORE_USB_STACK.
Production (LOG=n, ASSERT=n, RTT=n, reboot-on-fatal) is now the prj.conf
default; debug.conf is the opt-in bundle. Removed prod.conf and the
logging.conf auto-include; relocated RTT/ASSERT out of the always-on
platform confs so they no longer override the prod defaults.
Add CONFIG_ZEPHCORE_COMPANION_USB so the USB CDC companion transport
compiles independently of logging (default-y on USB-capable companions,
opt-in on ESP32-S3 via esp32s3_usb.conf). Gate all USB sites behind one
ZEPHCORE_USB_STACK macro.
Rework BLE/USB interface arbitration to first-come-first-served: neither
transport evicts a live session. Make active_iface mutation thread-safe
(mutex + atomic claim) across the BLE callback thread and USB workqueue.
Share the ESP32-S3 USB OTG / console DTS via common dtsi includes; enable
uart0 (GPIO43/44) on station_g2 and xiao so the console reroute works.
- src/Mesh.cpp Reverted #ifdef ZEPHCORE_COMPANION block → back to vanilla self_id.copyHashTo
- helpers/ContactInfo.h Removed OUT_PATH_SENT
- helpers/ui-joystick/joystick_defs.h Added OUT_PATH_SENT here (with comment clarifying it's UI-only)
- helpers/ui-joystick/joystick_ui_task.h Removed dead _next_batt_refresh field
- helpers/ui-joystick/joystick_ui_task.cpp Removed _next_batt_refresh(0) from ctor init list
- helpers/ui-joystick/joystick_screens.h MsgEntry::origin[80]→[32]; MAX_UNREAD_MSGS 32→16
- Kconfig DOOM help text now lists both UI activation paths
- ARCHITECTURE.md Same correction in §8.5
